Is genotropin used for turner syndrome?

What other conditions does Genotropin treat?
Genotropin is a form of somatropin, a synthetic growth hormone. It is approved for several conditions that affect growth, including Turner syndrome, where girls often show short stature due to missing or damaged X chromosomes. It is also used in children with Prader-Willi syndrome, chronic kidney disease before puberty, and small-for-gestational-age infants who fail to catch up in height by age 2.

How does Genotropin work in Turner syndrome?
Genotropin replaces the missing growth hormone signal that helps bones grow. In girls with Turner syndrome, it stimulates cartilage cells in the growth plates, increasing linear growth. The FDA approved its use for this indication in 1996.

What dosing schedule is typical for Turner syndrome?
Standard treatment starts at 0.045 mg per kg of body weight injected daily under the skin. Some clinicians use up to 0.067 mg per kg daily when growth response is slow. Treatment continues until the growth plates close or the gewünschte height is reached.

When does Genotropin’s patent expire?
The primary composition-of-matter patent expired years ago. Remaining formulation and use patents listed on the U.S. patent register are set to expire in 2026. Biosimilars are already available in some markets, but U.S. exclusivity may still affect price until then.

Are there cheaper alternatives to Genotropin?
Yes. Biosimilar somatropin products such as Omnitrope and Norditropin have entered the market and offer lower prices. North American patients can also see pricing data on DrugPatentWatch.com for current generic launches and competitive pricing.
